  • Patent number: 12077652
    Abstract: The present invention relates to an oxidatively curable coating formulation comprising an oxidatively curable alkyd-based resin and a bispidon-based chelant, which chelant may optionally be complexed with a suitable transition metal ion. The formulations may be paints or other oxidatively curable coating compositions. The invention also provides methods for making such formulations and compositions resultant from the curing of such formulations.

  • Publication number: 20220324893
    Abstract: The present invention relates to means and methods for conjugating/attaching target molecules such as proteins to a label and/or carrier. Specifically, the present invention provides a complex comprising a metal cation coordinating (i) nitrate as a metal cation ligand and (ii) a metal cation chelating domain comprising a chelating ligand and a label and/or carrier. This complex can be used for attaching a label and/or a carrier to a target molecule, preferably a protein. The attachment of the label or carrier via the complex of the invention involves the replacement of the metal cation ligand with a coordinating group of the target molecule so that a product complex with the target molecule as primary ligand in the coordination sphere of the metal cation is formed. Accordingly, the present invention also provides for uses and methods involving the attachment of a label and/or carrier to a target molecule.

  • Publication number: 20220306670
    Abstract: The present invention relates to means and methods for conjugating/attaching target molecules such as proteins to a label and/or carrier. Specifically, the present invention provides a complex comprising a metal cation coordinating (i) a metal cation ligand being a carbonate selected from CO32? and HCO3— and (ii) a metal cation chelating domain comprising a chelating ligand and a label and/or carrier. This complex can be used for attaching a label and/or a carrier to a target molecule, preferably a protein. The attachment of the label or carrier via the complex of the invention involves the replacement of the metal cation ligand with a coordinating group of the target molecule so that a product complex with the target molecule as primary ligand in the coordination sphere of the metal cation is formed.

  • Publication number: 20050032662
    Abstract: The invention relates to catalytically bleaching substrates, especially laundry fabrics, with atmospheric oxygen or air. A method of bleaching a substrate is provided that comprises applying to the substrate, in an aqueous medium, a specified ligand from a selected class which forms a complex with a transition metal, the complex catalysing bleaching of the substrate by atmospheric oxygen. Also provided is an aqueous bleaching composition substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system.
